•
Excessive voltage detected (battery voltage) at PIN 9 and 38 of the ENGINE connector.
Caution: the "lambda probe" parameter is not the actual read value but a recovery value is
displayed.
The instrument panel indicates this error by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Short-circuit to positive: with key ON, disconnect the sensor connector and measure the
voltage at PIN 1, wiring harness side (grey cable): if the voltage (5 or 12 V) is present, restore
the wiring harness, if the voltage is absent replace the lambda probe
P0155 Rear lambda probe heating
Electrical diagnosis:
•
short circuit to positive/ open circuit, short circuit to negative
Error cause:
•
Short-circuit to positive: an excessive voltage was detected at PIN 44 of the ENGINE con-
nector.
•
If open circuit, short circuit to negative: a voltage equal to zero was detected at PIN 44 of
the ENGINE connector.
The instrument panel indicates this error by lighting up in a fixed manner the MI warning light.
Troubleshooting:
•
Short-circuit to positive: disconnect the probe connector and check the correct sensor re-
sistance: if Not OK, replace the sensor; if OK, restore the wiring harness (Green/Red cable).
•
If open circuit, short circuit to negative: check the continuity from the probe connector (PIN
3 and 4) to the probe: if NOT OK, replace the probe; if ok, perform the check procedure for
the sensor connector and for the Marelli control unit connector: if NOT OK restore; if OK,
with the key ON and the sensor connector disconnected, check if there is battery voltage at
PIN 4: if NOT OK, check the continuity of the Red/Brown cable between the probe connector
and the injection relay (no. 17 in the electrical circuit diagram, position under the tank, on
the left side of the filter housing; however, CHECK the relay identification with the cable
colours); if there are also errors regarding the coils, injectors and secondary air, check the
relay and its energy and power line; if there is voltage at PIN 4, check ground insulation of
the Green/Re cable (PIN 3): if NOT OK, restore the wiring harness; if OK, check the con-
tinuity of the Green/Red cable (between PIN 3 of the sensor connector and ENGINE PIN
44) and restore the wiring harness.
WARNING
The control unit does not detect the following malfunctions of the lambda probe circuit relative
to the signal: interrupted circuit, short circuit to ground or malfunction of the sensor (for ex-
ample, voltage not variable). If the indication is abnormal, perform the troubleshooting indicated
below.
